* crypto/fsl: Make CAAM transactions cacheableSaksham Jain2016-03-29-0/+16
| | | | | | | | | | | | | | | | | | This commit solves CAAM coherency issue on ls2080. When caches are enabled and CAAM's DMA's AXI transcations are not made cacheable, Core reads/writes data from/to caches and CAAM does from main memory. This forces data flushes to synchronize various data structures. But even if any data in proximity of these structures is read by core, these structures again are fetched in caches. To avoid this problem, either all the data that CAAM accesses can be made cache line aligned or CAAM transcations can be made cacheable. So, this commit makes CAAM transcations as write back with write and read allocate. Signed-off-by: Saksham Jain <saksham.jain@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

* drivers/crypto/fsl: disable RNG oscillator maximum frequency checkAlex Porosanu2015-08-03-2/+2
| | | | | | | | | | | | | | | | | The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

* | imx6: Added DEK blob generator commandRaul Cardenas2015-03-02-7/+256
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale's SEC block has built-in Data Encryption Key(DEK) Blob Protocol which provides a method for protecting a DEK for non-secure memory storage. SEC block protects data in a data structure called a Secret Key Blob, which provides both confidentiality and integrity protection. Every time the blob encapsulation is executed, a AES-256 key is randomly generated to encrypt the DEK. This key is encrypted with the OTP Secret key from SoC. The resulting blob consists of the encrypted AES-256 key, the encrypted DEK, and a 16-bit MAC. During decapsulation, the reverse process is performed to get back the original DEK. A caveat to the blob decapsulation process, is that the DEK is decrypted in secure-memory and can only be read by FSL SEC HW. The DEK is used to decrypt data during encrypted boot. Commands added -------------- dek_blob - encapsulating DEK as a cryptgraphic blob Commands Syntax --------------- dek_blob src dst len Encapsulate and create blob of a len-bits DEK at address src and store the result at address dst.
